interview question how does application connects to device

[Paraneetharan Chandrasekaran]

I think the thread originator is asking about how the application knows
which device file to read or write.
This is done by h/w management system udev. udev creates/manages device
nodes in /dev/ dir and notifes applications based on the udev rules written
(via HAL events or DBUS signals).

Thanks,
